Homework Sourse1042 The pressure above atmospheric pressure of blood in a p
10.4.2) The pressure above atmospheric pressure of blood in a person\'s head and in their feet when standing is 50 mm Hg in their head and 180 mm Hg in their feet. Explain whether these numbers make sense. Note: 780 mm Hg = 1.0x105 N/m2 = 1 atm.
Solution
The pressure in person\'s head and feet are over and bove atmospheric pressure.
In the head the blood pressure will be due to its flow. (Rate of change of momentum due to mass flow per unit area)
In the feet the blood pressure will be due to its flow and due to pressure component of gh due to height.
